Color and Shape Feature Extraction and Matching in Pill Identification Systems Dr.E.Annasaro

Abstract-Image mining is the concept used to detect unusual patterns and extract implicit and useful Informations.Mining Image data is one of the essential features in the present scenario. Image data is the major one which plays vital role in every aspect of the systems like business for marketing, hospital for surgery, engineering for construction, Web for publication and so on.Image mining is an extension of Data mining.This paper describes about the implementation and tests to determine whether a given pill is legal or illegal based on the feature retrieval like shape, color, text etc. In this paper color and shape feature extraction were performed with color histogram for color feature and geometrical gradient vector algorithm for the shape. The color and shape feature of the pill is compared only which is matched with text feature. The pills matched with all the features like text, color, shape is said to be legal pill and mismatch with any one of the feature is declared as illegal pill
